Multi video cards + TV Tuner on XP Home/Pro?

Any of you guys' trading computer have:
a. 2 or more video cards
b. One of the cards is also a TV Tuner or Multimedia card or, you have an additional card which is a TV Tuner
c. Running on XP Home or XP Pro

The model of your video cards and tuner + whether you are running Home or Pro would be appreciated. TIA!

(I'm having a problem with MetaStock Pro graphics which their tech has been unable to pinpoint. It seems to be OK in XP Home, but I've only tested it on single video card system.)
